Four of us (estimated total people weight plus bags about 400kg) went to Tauranga on Wednesday in my 2016 Nissan LEAF with a 30kWh battery.

It was hot so we had the air con on the whole time, set to 19C. Music was being played on the Bose sound system from bluetooth-connected phones.

Auckland to Thames was 100% to 31%. (108km) Then charged 26 mins to 95% for 16.2kWh.

Thames to Greerton (Tauranga) then to Bayfair Mall (Mt Maunganui) was 95% to 19%. 127km - then charged 31mins to 95% for 20.4kWh.

Return leg - Bayfair Mall to Thames Public Library (via Greerton) - 95% to 19% (127km) - then charged 31mins to 90% for 19.7kWh

...and the home to Auckland (108km - slightly uphill), starting on 90% and arriving on 17%.

So total charging time during each leg was 26 mins and 31mins. The first leg was less charging because we had started on 100%. During each of the stops we had (respectively) breakfast and supper, which we would have done anyway. That's how we roll. Speedwise, I drove as fast as everyone else and used the aircon and played the tunes.....and we had a great day!

I didn't bother topping off after fast charging at Bayfair Mall (as I used to do with 24kWh LEAF) because I've done it a few times now, the Thames charger opened (used to go via Hamilton) and i knew we had more than enough to get to Thames.

It's very easy travelling and relaxed for all four of us. Had to pay at all 3 charge.net fast chargers. Total cost was $35.90.

My wife and I went for a leisurely drive this afternoon from Greenlane to Papakura and back. She was particularly keen to avoid the motorway as we live near it and hear every emergency siren go past day and night. This seems to enhance any sense we might have of the motorway being an unreliable way to get where we're going. One fool behind the wheel......and all traffic stops, possibly for hours.

So I set Google Maps for Papakura....and told it to avoid highways.

We went south via Mt Wellington and Panmure, to Botany and Howick and Dannemora, to Ormiston and Flat Bush and then Takanini and finally to Papakura. We had a wander around and a late lunch. Then we drove back up Great South Road.

The round trip was 63.0km. I'd started on 100% battery and finished on 71%.

Using 29% battery for 63km is 2.17km / 1% of battery. Multiply that out and you have 217km range for the city driving conditions along the route we took. That's pretty good. You could drive Auckland to Tauranga non-stop (202km) under the same conditions.

As for the car itself, adding the actual distance travelled to the GOM estimate of remaining range (63 actual +158 estimated remaining) gives a possible range of 221km. The variation with the 217km number will be a product of where I was between 71% and 72% battery. The car knows. I don't. Plus the next time I put my foot on the brake and regen....it can improve....or I put my foot down on the accelerator.....it can decline.

I find this fascinating and it's one of the reasons I enjoy driving an electric car: you need to build a new base of experience and learn new things. I'm loving that.

I have found similar results with my Leaf (30kw) Getting just over 2km per 1 % around towns. great fun to drive Happy new year and looking forward to more fast chargers in the

middle of the Island

Hey gulfa and Linux - what fuel economy is your Leaf reporting in km/kWh around town? Back of envelope calculation would suggest around 7 km/kWh? (assuming 28.5 kWh usable)

I've got 8.3 km/kWh on my 2013 Leaf over the course of ~3000 km around Christchurch.

Chch is mainly flat so I'm not surprised you're seeing consistently great efficiency. Well done!! :-) Auckland is fairly hilly.....some steepish and others are long-ish steady slopes up from sea level (or back down again). The motorway can kill your efficiency if you use it and I do most days if it's not too busy. But I'll generally fluctuate between 7.5 and 8 km / kw. I tend to reset it every time I charge.

Hey thanks. 7.5-8 pretty impressive around Auckland. Anyone from Welly?

Clearer knowing the km/kWh than km/1% - many readers here know how much 1 kWh costs, and avoids problem of 1% varying by battery capacity (1% on a P100D very different from 1% on a Leaf!).

I think the reason Linuxluver focuses on km per % is that its more pressing what the actual range is, than what the cost is. The cost per km in an electric car is negligible compared to an ICE, but range is still an issue with the 30 kW Leaf (for longer stretches of driving).

Looking forward to the day when EVs have the same (or better) range than ICEs at affordable prices. Next version of Leaf will be better, as will many other mid size EVs.

Good point webhead. % used for EV because that's what the dashboard reports. Better if it reported kWh remaining. With fuel economy in km/kWh (and not km/1%) and total capacity in kWh (instead of 100%), our EV conversations would be better informed.

You can drive with LeafSpy turned on as you go and it will log everything. I haven't tried this. I should.....but so far can't be bothered.

My current LEAF shows me energy information instantantioulsy, but I can't get a kw-used number easily. I would have to derive it or get LeafSpy measurements before and after.

The new 41kWh Renault Zoe is pretty much there right now. 400km range. Under NZ$40k imported. But it takes most of two hours to charge fully via a (relatively uncommon on Plugshare) 3-phase 22kw power source. They are common in industrial settings.......but haven't been implemented for the purpose of powering EVs. This may change.

But right now, the 41kWh Zoe is more than good enough range-wise and affordable.......It's just the time it takes to charge if you're on a road trip. I'm tempted to buy one............but then it reduces the cash I'll need for the Tesla Model 3....and my 30kWh LEAF is a sweet spot right now: decent range, fast to charge, utterly reliable.

I leave the OBD turned on and enable LeafSpy most times I go for a drive. Bit of a hassle as you imply, I'd have less use for LeafSpy if the car's dashboard reported kWh remaining.

I'll try that tomorrow. I have a second phone I can use just for LeafSpy.

From a newbie... just about to purchase a Leaf, wondering if anyone has any thoughts on the battery report the dealer has sent through:

Are the number of red bars a concern?

[Hope the image link works]

Thanks

Electric cars are getting interesting. But ranges in the 150-200km zone followed by hours to recharge aren't nearly enough to tempt me off fossil fuels at current pricing. I don't do a lot of long trips, but I do the off few, and constant range anxiety, wondering where charge points were, and potentially waiting for hours to recharge wouldn't work for me.

I doubt my next car will be an electric one.

However, the car after the next one might be. I see Here that Samsung now appear to have a battery pack good for 372 miles (nearly 600km) on a charge, and which can regain 310 miles (circa 500km) of charge on just 20 minutes of charging. Mass production set to start in 2021.

With those stats I would be seriously interested. Enough to drive from Wellington to (say) Taupo with the aircon on most of the way, stop for 45 minutes for lunch while the car charges, then press on to Auckland. If that was cost competitive with a petrol car, and the battery pack had a reasonable lifespan, then I would be in. Particularly if it had zippy performance like some of the Tesla models.

So, maybe in the mid-2020s, I will go electric.

Looks like a very fine battery to me. What year?

a) SOH 99% indicates it's still got 99% of the original capacity i.e. minimal wear

b) 2 QCs: Consistent with minimal wear. Debated but lots of quick charging probably wears the battery faster than L1/L2 charging.

c) red cells: this simply indicates the cells that were active at the time (http://www.electricvehiclewiki.com/Leaf_Spy_Pro for more info)
